DRAFT-RIGGING FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Feb. 12, 19118.

Original application ftled April 18, 1914, Serial No. 832,689. Dividedand this application led September 28, 1915. Serial No. 53,111.

To all whom it may concern:

Bc it known that I, WILLIAM H. MrNnn, a. citizen of the United States,residing at Chazy, in the county of Clinton and State of New York, haveinvented a certain new and useful Improvement in Draft-Riggings forRailway-Cars, of which the following is a full, clear, concise, andexact description, reference being had to the accompanying drawings,forming a part of this specification.

This invention relates to improvements in draft riggings forrailway-cars, and this application constitutes a division of myapplication 832,689, filed April 18th, 1914, for improvements in draftrggings for railway cars.

The object of the invention is to provide an improved draft rigging forrailway cars and more particularly improved stop members.

In the drawing forming a part of this specication, Figure 1 is alongitudinal vertical sectional view of a draft rigging showing myimprovement in connection therewith. Fig. 2 is a vertical transversesectional view taken substantially on the line 2 of Fig. 1. And Fig. 3is a detailed perspective showing a section of one of the stop memberswith the novel strengthening or bracing means attached thereto.

In said drawing, 10-10 denote the center or draft sills of a car, 11 thedraw-bar and 12 the combined friction shell and spring casing. Themember 12 has a friction cylinder proper 13 and a spring casing proper14. Cooperating with the cylinder 13 are friction shoes 15 and wedgelG.Mounted within the spring casing 14 are Vertical twin arranged mainsprings 17-17, each consisting of a heavy outer coil and a nested innerlateral coil. At the front ends of the spring 17 is a movable follower18 having a forwardly extended cylindrical flange 19 which slides withinthe cylinder 13. Interposed between the follower 18 and the frictionshoes is a preliminary spring 20, and the friction elements, preliminaryspring and follower 18 are held in assembled position by means of a bolt21. The rear end of the spring casing 14 is open and has slidablymounted therewithin a rear follower 22, said follower 22 having arearward extension 23 through which extends a key 24. The key 24 isslidably mounted within suitable elongated slots in the draft members 10and said key is operatively connected with the draw-bar 11 by means oflinks 25 and coupler key 26, the latter also sliding in elongated slotsin the draft members 10. The side walls of the spring casing 14, attheir rear ends are also slotted as indicated at 27 to accommodate theforward movement of the key 24. lVhere the spring casing 14 unites withthe friction cylinder 13, shoulders 28 are formed which engage the frontstops, hereinafter described. All of the foregoing parts are the 'sameas those shown and described in my said application 832,689, to whichreference is hereby made for a more detailed description of theoperation of the gear.

The gear proper is supported between an upper stop member A and a lowerstop member B, each of said members A and B, as shown, being in the formof a commercially shaped channel iron, the member A having the flanges29 thereof extended upwardly and riveted or otherwise suitably securedto the members 10, whereas the member B has its ianges 30 turneddownwardly and detachably secured to the draft members 10 as by bolts 31or other suitable means. Each of the members A and B has a verticallyarranged opening 32 therein within which is adapted to be received thespring casing 14. To strengthen the members A and to also form moreefficient stop shoulders, each of the transversely extending front andrear portions 33 and 34 of the members A isprovided with a substantiallyU shaped clip 35 having parallel arms 36-36 fitting over the sections ofthe members A and B and secured thereto as by rivets 37-37. The innerfaces of the clips are vertically elongated, as clearly illustrated inFigs. 1 and 3 to thereby provide a wider bearing for the spring casingan-l the rear follower 22. With this construction, I form rigid frontand rear stop shoulders, the same being so arranged as to minimize anytendency of the web portions of the channels A and B being bent orturned.

As most clearly shown in Fig. 2, the spring casing is provided withlongitudinally extending flanges 38-38 on the sides thereof which restupon flanges 39-39 struck upwardly from the web portion of the lowerchannel stop member B.

In assembling the device, the stop mem ber A is first permanentlysecured to the v proper are inserted.\ the stop draft members with theclips 35 attached thereto after which the links and gear memberB beingfinally attached to the`s1lls. The whole structure affords an efficientgear and one which may be 'readily inspected` for repairs etc.

I c aim:

1. In a draft riggingfor railwa cars, stop members comprlsing upper anmembers, and provided with vertical slots adapted to receive a draftgearthe members formin the ends of the slots being provided wit a Ushaped clip forming stop shoulders for the draft gear. A

2. A stop member for draft riggings lower having an opening thereinadapted to reoeive a draft gear, the edges of said opening at the endsof the gear bein reinforced by U shaped clips forming shou ders.

3. A stop member for draft riggings, comprisin a channel member havingan opening t rough the web thereof, and U shaped lclips secured to theweb at the ends of said opening, said clips each having a Wide bearinginner face adapted to form a stop shoulder.
